| hypothesis | an educated guess |
| Inference | a conclusion reached on basis of evidence and reasoning |
| Observation | the action or process of closely observing or monitoring something or someone. |
| Variables | an element, feature, or factor that is liable to vary or change. |
| controls | an element that remains unchanged or unaffected by other variables |
| independent variables | One thing that is changed in the experiment |
| dependent variable | The thing that you measure in the experiment |
| controlled/constant variable | All the things that remain the same in the experiment |
| repeated trial | doing the experiment more than once to improve accuracy of results |
| energy | the capacity to do work |
| kinetic energy | the energy an object has because it is moving |
| potential energy | the energy stored in something because of its height above the ground, or because it is stretched or compressed, or in a chemical form |
| insulator | a substance or material that does not allow heat to pass through it easily (rubber and plastic) |
| conductor | a substance or material that allows heat to pass through it easily (gold, metal) |
| organelle | any of a number of organized or specialized structures within a living cell. |
| cell membrane | Controls what comes into and out of a cell; found in plant and animal cells |
| cell wall | Rigid outer layer of a plant cell |
| cytoplasm | Gel-like fluid where the organelles are found |
| mitochondria | Produce the energy a cell needs to carry out its functions |
| vacuoles | Store food, water, wastes, and other materials |
| chloroplasts | Capture energy from the sunlight and use it to produce food (glucose) in a plant cell |
| Ribosomes | Assemble amino acids to create proteins |
| nucleus | Contains DNA, which controls the functions of the cell and production of proteins |
| lysosome | Uses chemicals to break down food and worn out cell parts |
| eukaryotic | organisms whose cells contain a nucleus and other membrane-bound organelles |
| prokaryotic | organisms whose cells lack a nucleus and other organelles |
| unicellular | characterized by the formation or presence of a single cell or cells. Consisting of a single cells |
| multicellular | having, made up of, or involving more than one and usually many cells especially of living matter |
| specialisation | the process of concentrating on and becoming expert in a particular subject or skill |
| energy transfer | the movement of energy from one place or object to another (kicking a soccer ball) |
| radiation | one of the three ways that thermal can travel, and the only way heat can travel through a vacuum |
| convection | the flow of thermal energy through a fluid material by the movement of the material itself, often caused by temperature differences |
| energy transformation | changes from one kind of energy into another kind of energy (on a swing goes from gravitational to kinetic energy.) |
| energy chains | Energy transfer- goes from moving leg (kinetic energy) to another object a soccer ball |
| conduction | the process by which thermal energy travels through a material or between materials from hot regions to cooler regions by the Collison's of molecules. |
